Abstract (en)
Of particular application in digital processing systems that require oversampling. As a first step in the method a derivative of generic order "n" of the input signal to be interpolated is taken; subsequently the interpolation process itself takes place on the samples of the n-th derivative of the signal, and finally integration of the previously interpolated signal, to the same order "n" as the derivative is done. The device implements the method described. <IMAGE>
